I scan for multiple domains and a fairly large range of types of mail
with only 1 bayes db without a problem. I would recommend providing a
suitable method for users to train mail (A shared IMAP folder for
example. There are some ideas in the wiki)

I would also suggest you search the archives for a series of post that
Matt Hampton and I exchanged a few months ago about doing this. We
had it running but from my point of view it was using more resources
and hence slowing the box more than the native MS set up but it did do
